Available in PDF, EPUB and Kindle. Book excerpt: Zeolites form a family of minerals which have been known since the 18th century, but they remained a curiosity for scientists and collectors until 60 years ago, when their unique physicochemical properties attracted the attention of many researchers. In the past 30 years there has been an ex traordinary development in zeolite science; six International Conferences on Zeolites have been held every 3 years since 1967, and a large number of interesting contributions have been published in their proceedings. Many books, written either by individual authors or by several authors under a leading editor, have been published on these interesting silicate phases, but none has been devoted specifically to natural zeolites, even though this theme may be of interest not only to earth scientists, but also to chemists, as the in formation obtained from natural samples completes and in tegrates the characterization of many zeolites. We are trying to fill this gap on the basis of 20 years of research on natural zeolites, which we performed at the University of Modena together with many friends and colleagues. If it is in general difficult to write a scientific book with out upsetting somebody, this is particularly true for a book on natural crystals, because mineralogy is an interdisciplin ary science which covers some fields of physics, chemistry, it is almost impossible to meet every petrology, geology, and requirement.

Available in PDF, EPUB and Kindle. Book excerpt: Volume 45 of Reviews in Mineralogy and Geochemistry is a new and expanded update of Volume 4 from 1977. Most of the material in this volume is entirely new, and Natural Zeolites: Occurrence, Properties, Applications presents a fresh and expanded look at many of the subjects contained in Volume 4. There has been an explosion in our knowledge of the crystal chemistry and structures of natural zeolites (Chapters 1 and 2), due in part to the now-common Rietveld method that allows treatment of powder diffraction data. Studies on the geochemistry of natural zeolites have also greatly increased, partly as a result of the interests related to the disposal of radioactive wastes, and Chapters 3, 4, 5, 13, and 14 detail the latest results in this important area. Until the latter part of the 20th century, zeolites were often looked upon as a geological curiosity, but they are now known to be widespread throughout the world in sedimentary and igneous deposits and in soils (Chapters 6-12). The application of natural zeolites has greatly expanded since the first zeolite volume. Chapter 15 details the use of natural zeolites for removal of ammonium ions, heavy metals, radioactive cations, and organic molecules from natural waters, wastewaters, and soils. Similarly, Chapter 16 describes the use of natural zeolites as building blocks and cements in the building industry, Chapter 17 outlines their use in solar energy storage, heating, and cooling applications, and Chapter 18 describes their use in a variety of agricultural applications, including as soil conditioners, slow-release fertilizers, soil-less substrates, carriers for insecticides and pesticides, and remediation agents in contaminated soils.

This book was released on 2012-12-06 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than seventeen years have passed now since Glauco Gottardi and Ermano Galli 1 have published their remarkable book on «NATURAL ZEOLITES» where properties and features of naturally occuring phases then available have been compiled. Several new natural zeolites have been found since then, but also natural counterparts ofzeolites which have only been known as synthesis products. The natural formation conditions of zeolites could only be deduced and estimated from their geological environment at the time when NATURAL ZEOLITES has been published, as zeolite synthesis was mainly focused on procedures at low pressures such as those introduced by Barrer and co workers'. Natural zeolites, however, had only been obtained "occasionally" and systematic study to reconstruct these formation conditions has not been performed ever since. This book is focused on the synthesis of natural zeolites by simulating the natural synthesis conditions in the laboratory which are essentially different in means and results from those obtained by conventional synthesis methods. Although the synthesis in the laboratory has undoubtly a great number of advantages over nature such as the employment of proper precursors or the choice of pressure and temperature in a wide range, the synthesis time is very limited in respect to natural conditions: synthesis times ofyears or even tens ofyears which would be necessary to obtain synthesis results for some zeolites- e.g. at 4°C (deep sea conditions) are rather unrealistic.

This book was released on 2018-12-17 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 4 of Reviews in Mineralogy was prepared to serve as notes for a short course on the Mineralogy and Geology of Natural Zeolites held in Seattle, Washington, November 4-6, 1977. The title of the short course reads Natural Zeolites; however, the subject matter treated in the course and reviewed here deals primarily with those zeolites that occur in sedimentary rocks and which have formed by authigenic or burial diagenetic processes. Unfortunately, only limited coverage has been given to the classical occurrences of zeolites--the megascopic crystals in the vugs and cavities of basalts and other basic igneous rocks. Our only justification is that since the late 1950s, almost all major efforts on zeolites have been directed towards the "sedimentary" occurrences, and it is these occurrences of zeolites in sedimentary rocks that are still unfamiliar to many geologists and mineralogists. It is our intention that this short course and these notes will play a small role in alleviating this unfamiliarity.

Download or read book The Reconstruction of Natural Zeolites written by Habbib Ghobarkar and published by Springer Science & Business Media. This book was released on 2003 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zeolites have unusual properties and as a result they are some of the most interesting inorganic materials known today. In contrast to conventional nanomaterials, zeolites exhibit a long-term stable inner void system on the nanometer scale and their properties are almost independent from the crystal size.The Reconstruction of Natural Zeolites summarizes the known properties of natural zeolites and, importantly, shows how they can be synthesized by simulating the conditions of natural formation. Systematically, a direct correlation between the glassy precursor composition and that of the zeolite product is established. The zeolite crystal morphology obtained at given synthesis conditions allows direct conclusions on the conditions of formation in nature. This book is a valuable practical guide and tool for solid-state chemists, physicists, mineralogists and engineers. It will be of interest to:-materials scientists, -zeolite researchers, -mineralogists, -physical chemists, -bio-materials scientists, -inorganic chemists, -inorganic synthesis engineers, -advanced students in these disciplines. The Reconstruction of Natural Zeolites is written in a concise way in order to make it more accessible to the interested reader. The images convey an impression of the beauty of this fascinating domain of advanced inorganic materials for high technology.
Download or read book Zeolites written by B. Držaj and published by Elsevier. This book was released on 2011-09-22 with total page 707 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis of zeolites with desired structure and properties is of great importance for the preparation of highly active and selective catalysts for inorganic and organic reactions. The zeolite matrix offers unique possibilities for carrying out molecular shape-selective catalysis and this places the zeolite matrices among the most successful tools used in molecular engineering on a large scale.These proceedings cover the most recent developments in the fields of synthesis, structure determination and technological use of zeolites. The papers give detailed explanations of the processes involved in the mechanisms of zeolite synthesis. Special attention is focussed on complex ionic equilibria which occur in the starting hydrogel, to the ``templating effect'' and to the kinetics of zeolite formation. New powerful methods for structure determination of these materials, which usually consist of small crystals, are presented e.g. neutron diffraction and X-ray diffraction using synchrotron radiation. The distribution of tetrahedrally coordinated framework-constituent elements and their interaction with adsorbates is revealed by using high magnetic field nuclear magnetic resonance with sample spinning at ``magic'' angle (MAS NMR).Quite a number of articles are devoted to the dependence of the physico-chemical properties of zeolites on the parameters set during their synthesis. Descriptions are given of the possible technological use of synthetic zeolites in the fields of adsorption, catalysis, the production of laundry detergents, the removal of radioactive wastes, and the technological use of natural zeolites in the fields of animal feeding, municipal water treatment, paper and cement production, and energy storage. This book will be of interest to scientists working in the fields of catalysis, surface science, inorganic chemistry, materials science, petrochemistry, solid state physics, crystallography and geology.

This book was released on 2021-10-20 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The publication of the books "Naturmineralien, Regulation und Gesundheit" and "Klinoptilolith-Zeolith – Siliziummineralien und Gesundheit" has led to a growing interest in the silicates natural zeolite, bentonite/montmorillonite and silicon dioxide (synonym: silicic acid) on the part of therapists and especially on the part of the consumers owing to the healthy and quality-of-life improving effect of the silicates. According to various studies, the trend to orientate towards natural remedies leads to a growing demand of more and more people. However, the reorientation towards other remedies involves several questions. This also applies to natural zeolite, bentonite, montmorillonite and silicon dioxide (silicic acid), partly because of wrong ideas about the silicates that are often spread without any criticism and that cause insecurity among the people. Silicates belong to the oldest remedies of mankind e.g. in form of clay and medical clay. In fact, 2,400 years of experience have been gained already. As the mechanisms of action and effects of such natural remedies are fundamentally different from those of traditional medical drugs, which are usually applied by conventional medicine, the need for knowledge is exceptionally great here. The number of requests that we have received almost daily over ten years proves that. This enormous interest has inspired us to answer the questions in written form and publish them as a book in order to satisfy the "thirst for knowledge" with regard to natural zeolite, bentonite/montmorillonite and silicon dioxide (silicic acid). All the answers to questions from everyday life are, for the most part, put in easy terms for reasons of a better understanding. At the same time, however, they reflect the current scientific state of knowledge.
